Today on Wednesday’s Wonderful World of Wikipedia is the concept ofLibration. In astronomy libration (from the Latin verb libro -are “to balance, to sway”, cf. libra “scales”) refers to the various orbital conditions which make it possible to see more than 50% of the moon’s surface over time, even though the front of the Moon is tidally locked to always face towards the earth. As the orbital processes are repetitive, libration is manifested as a slow rocking back and forth (or up and down) of the face of the orbital body as viewed from the parent body, much like the rocking of a pair of scales about the point of balance.
On this special Halloween edition of Wednesday’s Wonderful World Of Wikipedia, I link to the living dead. This article is of particular intrest because of the discussion around the differences between the zombies in Romero’s Dead Series movies versus Russo’s Living Dead Series movies.
This week on Wednesdays Wonderful World of Wikipedia is Bacon Number. The Bacon number of an actor or actress is the number of degrees of separation they have from actor Kevin Bacon, as defined by the game known as Six Degrees of Kevin Bacon. The computation of a Bacon number N for X is a “shortest path” algorithm. It involves computing the Bacon number for all film actors who X has acted with. Notably Bacon is not the most linkable actor. That honor goes to Rod Steiger. The average Steiger number in the acting community is 2.679. By contrast, the average Bacon number is 2.946.
